Ulcerative Colitis follows a prolonged course with periods of activity ( relapse) and inactivity ( remission). A majority of the cases respond to medical treatment and do not require surgery. Patients diagnosed with ulcerative colitis should be on a regular follow up. If the disease is MORE THAN 10 YEARS old and has involved the whole of the colon then chances of COLONIC CANCER INCREASE. These patients should be REGULARLY SCREENED for the same.
